Embodiment 1
[0014] Implementation Example 1: Titanium products formed by gel ultrasonic vibration.
[0015] 1. Mix 90ml hydroxyethyl methacrylate and 270ml toluene, add 0.03g benzoyl peroxide;
[0016] 2. Add titanium hydride powder with an average particle size of 5 μm into the premix, then add 3.6ml of oleic acid and 3.6ml of polyethylene glycol-400, and stir evenly to obtain a stable slurry;
[0017] 3. Add 3.6ml of dimethylaniline, stir quickly and evenly, inject into the ultrasonic vibration mold, and vibrate continuously at 20KHz for 5 minutes;
[0018] 4. After the shaking, take out the green body from the mold, and dry it in an electric blast drying oven at 70°C for 1 hour. The finally obtained green body has no pore defects and has a solid content of 54vol.%.
Embodiment 2
[0019] Implementation example 2: gel ultrasonic vibration forming stainless steel products.
[0020] 1. Mix 158ml hydroxyethyl methacrylate and 40ml toluene, add 1.7g benzoyl peroxide;
[0021] 2. Add stainless steel powder with an average particle size of 20 μm to the premix, then add 1.98ml oleic acid and 0.99ml polyethylene glycol-400, and stir evenly to obtain a stable slurry;
[0022] 3. Add 1.98ml of dimethylaniline, stir quickly and evenly, inject it into the ultrasonic vibration mold, and vibrate continuously at 25KHz for 30 minutes;
[0023] 4. After the shaking, take out the green body from the mold, and dry it in an electric blast drying oven at 100°C for 5 hours. The finally obtained green body has no pore defects and has a solid content of 55vol.%.
Embodiment 3
[0024] Implementation example 3: Gel ultrasonic vibration forming YG8 cemented carbide products.
[0025] 1. Mix 120ml hydroxyethyl methacrylate and 120ml toluene, add 0.17g benzoyl peroxide;
[0026] 2. Add YG8 cemented carbide powder with an average particle size of 3.4 μm to the premix, then add 0.168ml oleic acid and 0.108ml polyethylene glycol-400, and stir evenly to obtain a stable slurry;
[0027] 3. Add 0.168ml of dimethylaniline, stir quickly and evenly, inject into the ultrasonic vibration mold, and vibrate continuously at 40KHz for 15 minutes;
[0028] 4. After the shaking, take out the green body from the mold, and dry it in an electric blast drying oven at 80°C for 3 hours. The finally obtained green body has no pore defects and has a solid content of 57vol.%.
